Hard water refers to water (H2O) that contains a relatively high concentration of dissolved mineral salts, such as magnesium and calcium. These dissolved salts are often undesirable, as they can precipitate as insoluble solids, causing mineral buildup.

∙ 11y agostandard hard water is prepared in lab during soap titration method. when 1gm of calcium carbonate is dissolved in minimum quantity of HCL. then it is heated to dryness and the residual is dissolved water to make 1L solution.

When hard water is heated, the carbonates precipitate out of solution, which forms scales in pipes. As a result, this will narrow and possibly clog your pipes. Scale prevents efficient heat transfer, so a water heater with scale will have to use a lot of energy to give you hot water.

How hard water Is produced?
You might be talking about ice but hard water is sourced from limescale rock and the limescale is in the water and that is what you get in your kettle when you dont filter the hard water.
What is standard hard water?
hard water is which has no ability to lather with soap standard hard water contains 1mg of calcium carbonate in every 1ml of water.
Is hard water safe?
No. Hard water is water with high amounts of dissolved calcium and magnesium.
What minerals are in hard and soft water?
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
How do you make permanent hard water soft?
Hard water is the one that does not lather with soap. Permanent hard water can be converted to soft water by adding sodium carbonate (Na2CO3), or calgon or zeolite.

Is the hardness of water same everywhere?
No. There is different types of hard water.There is slightly hard, moderately hard, hard and very hard water.And as for soft water it has to have less than a grain of calcium or magnesium. Hard water isn't as useful as soft water.
What is standard hard water?

hard water can be converted to soft water by boiling, filteration etc.
How does hard water differ chemically from soft water?
Hard water has more calcium than soft water does
